How to Choose the Right SPF for Your Skin.

Lets begin with understanding what SPF & PA mean? 

UV protection is measured by SPF (Sun Protection Factor) and PA (Protection Grade of UVA). 

SPF indicates the level of protection against UVB rays, which are primarily responsible for causing sunburns. An SPF of 30 blocks about 97% of UVB rays, while higher SPFs provide slightly more protection. However, it's important to note that no sunscreen can block 100% of UVB rays, so reapplication is key for prolonged sun exposure.

PA rating, on the other hand, indicates the level of protection against UVA rays, which penetrate deeper into the skin and contribute to premature aging and skin cancer. PA ratings range from PA+ to PA++++, with higher ratings providing better protection against UVA rays.

The best sunscreen is sunscreen above SPF 30 with a PA rating of ++++.

Now that you have understood SPF & PA, let's begin to understand UV rays.

UV rays, or ultraviolet rays, are invisible rays emitted by the sun. 

There are three types of UV rays- UVA, UVB  & UVC.

1. UVA (Ultraviolet A) Rays: UVA rays have longer wavelengths and can penetrate deep into the skin. They are the primary cause of skin aging and can contribute to the development of skin cancer. UVA rays are present throughout the day, even on cloudy days, and can penetrate glass windows.

1. UVB (Ultraviolet B) Rays: UVB rays have shorter wavelengths and primarily affect the outer layers of the skin. They are the primary cause of sunburn and play a key role in the development of skin cancer. UVB rays are strongest during midday hours and in the summer months.
2. UVC (Ultraviolet C) Rays: UVC rays have the shortest wavelengths and are the most harmful, but fortunately, they are mostly absorbed by the Earth's ozone layer and do not reach the surface.

To fight these UV rays, you need to  use a broad-spectrum sunscreen.

But Sun rays are the natural source of Vitamin D, then why shall one use sunscreen and block Vitamin D from entering the body?

While it's true that sunlight is a natural source of Vitamin D, it's essential to balance sun exposure with sun protection to minimise the risk of skin damage and skin cancer. 

Sunscreen does block some UVB rays, which are responsible for stimulating Vitamin D production in the skin. However, even when wearing sunscreen, the body can still produce Vitamin D, although at a slightly reduced rate. Using sunscreen helps protect the skin from harmful UV damage while still allowing some Vitamin D synthesis to occur.

However, the best time to go under the sun without sunscreen to get Vitamin D is from morning 7 am to 9 am. But one shall limit the exposure upto maximum 15 minutes without sunscreen.

Why are some sunscreens more preferred over other sunscreens available in the market?

So let's admit that minimal to almost zero white cast means extra protection.

Ever heard of "Hybrid Sunscreen" but unsure of its meaning?

A hybrid sunscreen combines the benefits of both mineral and chemical filters, offering broad-spectrum protection against harmful UV rays. This innovative formulation typically incorporates active ingredients like zinc oxide and titanium dioxide alongside chemical filters. By blending these elements, hybrid sunscreens provide effective sun protection while minimising the white cast often associated with mineral sunscreens. Their versatile nature makes them suitable for various skin types and activities, making them a popular choice for daily sun protection. 

Why are doctor’s & brand’s emphasising the importance of using a Sunscreen?

Daily application of sunscreen is imperative to shield your skin from the harmful effects of sun exposure. Without adequate protection, UV rays can result in sunburns, premature aging, and heightened susceptibility to skin cancer. Furthermore, the depletion of the ozone layer, exacerbated by escalating pollution levels, underscores the urgent need for consistent sunscreen use to safeguard skin health.

Protection against Blue Light.

Wearing sunscreen is recommended to protect against blue light due to its potential to cause skin damage. Blue light, emitted by electronic devices and indoor lighting, can penetrate the skin and generate free radicals, leading to oxidative stress and premature ageing. By incorporating sunscreen into your skincare routine, you create an additional barrier against the harmful effects of blue light, helping to maintain skin health and vitality.
